CORPORATION OF DELAWARE BOOT-TREE:

Application filed December 3, 1928. Serial No. 323,299.

This invention relates to improvements in' bootvtrees or lasts of the type employedin the manufacture of rubber'boots, and in whichthe lasts are preferably constructed of metal and have a toe sectionwhich is separaiy ble from the leg sectionto facilitate the re-' movalof the last from the completed boot.

The object of the invention is to provide a boot tree or last of the type mentioned, of

strong and durable construction, the toe section havin a guide member rigidly secured thereto which; is slidable within another guide member which is pivotally mounted upon the leg section, and-a simple and efiicient means being provided upon the p1voted guide. member for interlocking. with the slidable guide member and thereby holding the toe and le sections in abutting relation.

Another ob ect of the invention is to so position the sl dable and pivoted guide members that in moving the toe section of the last upon theleg section thereof that the longitudinal-abutting faces of the toe and leg sections will slide, one upon the ether and a tongue provideduponthe toe section w ll be-guided between ways formed upon the leg section. H

Still another object of the, invention is to provide a means for forcing the abuttmg facesof the'toe and leg sections t1 htly together when said sections are locate n their normal orlocked position. p

The invention consists in a boot tree or last as set .forth in the following specification and particularly as pointed out in the claims thereoi. Referring to the drawings: Figure 1 represents a side elevatlon-of a boot tree embodying my invention, the leg section being broken away to save space in the drawings and the toe and leg sections being shown in their normal or locked position.

Fig. 2 is a sectional elevation of the lower portion of the boot tree, the toe section being shown inits extreme open posit on. V

Fig. 3 is a detail section taken on the line 3-3 of Fig. 1. i Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 represents a, main or leg section of a boot tree or last and 6 represents a toe'section. said sections having oppositely disposed abutting faces disposed in intersecting planes as indicated at A and B, theplane A being substantially lengthwise of the leg portion and the plane B being substantially perpendicular thereto. The 1e and toe sections are preferably hollow an constructed of aluminum.

Pivotally mounted on a in 7, which is locatedat the lower end of t' e leg section 5, is a guide member 8 having a dove-tail shaped groove 9 formed therein. A guide member 10, rigidly secured to the toe section 6, is slidably mounted in the groove 9. The guide members 8 and 10 are so positioned upon the leg and toe-sections respectively of the last that when said sections are located in their normal or closed position that a rear face 11 of the toe section will abut against a front face 12 of the leg section in the plane A. A' tongue 13, furthermore, projects rearwardly a short distance from the face 11 of the 'toe section 6 between ways 14 provided upon the leg section 5 and when the toe section is moved upon the leg section, this latter guiding'means co-operates with the guide members 8 and 10 in guiding the'movement of the toe section upon the leg section.

As it is desirable that there shall be some clearance between the guide members while the toe section is being moved upon the leg section, and. as it is also desirable that the looseness caused by the clearance shall be eliminated when the sections are locked together, a means is rovided for forcing-the opposite abutting aces of the toe and leg sections together when said sections are in their normal or closed position. This-mechanism is as follows :-Located at the front said members reach their uppermost position upon the leg section 5, and when the toesection reaches the extreme limit of its upward movement, the pressure of the roller 16 upon the front face of the guide member 10 will force the adjacent abutting faces 11 and 12 of the toe section 6 and leg section 5 respectively tightly against each other.

A pin 18 mounted adjacent to the top of the guide member 10 projects from the opposite sides of said guide member and contacts with the upper surface of the guide member 8 and thereby limits the downward movement of the member 10 upon the member 8.

Means are provided for locking the toe and leg sections in their normal or closed positions as follows :-Located in the rear surface of the guide member 10 is a recess 19 and mounted in a recess 20 provided in the guide member 8 is a spherical member 21 which is forced by a spring 22 into contact with the rear surface of the guide memberlO. When the toe section is located in its uppermost osition upon the leg section 5 and the adacent faces of said sections are contacting one with the other, the spring 22 will force the spherical member 21 into the recess 19 which, at this time, is located in alignment with the member 21 and the toe and leg sections will be locked together.

When it is desired to remove the last from the boot an eye member 23 at the top of the leg section 5 of the last is attached to a hook,

and a pull upon the leg portion of the boot' causes the leg section of the last to move out of the boot leaving the toe section 6 of the last in the toe portion of the boot until the oppositely dis osed faces of the toe and leg sections are disengaged from each other, whereupon the toe section 6 will swing rearwardly out of the toe portion of the boot, said.

toe section rocking upon the pivot 7 .into the position illustrated in Fig. 2, thereby permittin the entire last to be withdrawn throng the leg portion of the boot.

I claim:
